Hi the community,

I hope you are all fine and safe.

 

I'm using the Outlook desktop client with a MS365 licence.

 

I have added a pop3 account and when I send, in one time, more than 20 emails only the first 20 emails are sent, the rest of the emails remain in the Sending Box. If I close Outlook and reopen it, the next 20 emails are sent and so on.

 

Do you know what is the problem and how to solve it. Thank you

 

Regards

Mehdi
